关键词42：天然铀生产与供应

经历了 60 余年的发展历程，中国铀矿采冶产业已建立完整的科技研发、生产运营、人才队伍体系，拥有露天开采、地下开采、搅拌浸出、地表堆浸、原地爆破浸出、原地浸出等全套的铀矿采冶生产技术。进入 21 世纪，为确保天然铀的长期稳定供应，中国逐步完善了以“国内开 发、海外开发、国际贸易、战略储备”相互依托、灵活调节、稳定可靠的“四位一体”的天然铀供应保障体系。近年来，中国积极推进铀矿大基地建设，促进铀资源开发绿色、集约、高效发展。新疆、内蒙古等北方地区地浸项目全面建成投产，形成以北方绿色地浸砂岩矿山为主体、 南方硬岩矿山为补充的产业发展格局。

Keyword 42：Natural Uranium Production and Supply

 The past six decades have witnessed exponential growth of China’s uranium mining and milling industry. It now features an extensive network of research and development and production facilities, manned by a large team of experts, technicians, and skilled workers. A full range of uranium mining and milling techniques are employed, including open-pit and underground mining, agitated leaching, heap leaching, in-situ blasting, and in-situ leaching. Since the beginning of the 21st century, efforts to ensure long-term stability in the supply of natural uranium have included building a stable, flexible and reliable supply system that hinges on four pillars: domestic production, overseas development, international trade and strategic reserves. China has in recent years been actively building large bases for uranium mining and promoting a green, rational and efficient approach to developing uranium resources. Construction of major in-situ leaching projects in northern regions such as Xinjiang Uyghur Autonomous Region and Inner Mongolia Autonomous Region has been completed and they have been put into operation. A development pattern has thus emerged with in-situ leaching of sandstone-type deposits in northern China becoming the backbone of the industry and insitu leaching of hard rock deposits in southern China assuming a supplementary role.
